Mexican flood victims fought for food and medicine today, as workers continued efforts to rescue 20,000 still stranded on rooftops, the AP reports. Some camped on upper floors or roofs to guard possessions, while others went looking—some looting—for food. One worker said rescuers were focusing on "selective evacuations," mostly of the sick, and dropping supplies in remote towns.

Flooding has overtaken 80 percent of the Gulf Coast state of Tabasco since rivers first overflowed about a week ago. The state capital, Villahermosa, remains underwater, where garbage has stacked up since public services were cut. Two more bodies were found yesterday, bringing the region's death toll to 10. President Felipe Calderon called the scene "grave" but vowed that the worst was over.
